Log message:
Note that the need for this patch appears self-induced.

Log message:
On systems where both of the conditions

1. LD_LIBRARY_PATH does _not_ take precedence over DT_RPATH
   (e.g. Linux)
2. A previous libpython with the same major.minor is already installed
   (e.g. a previous version of this package)

hold, the built python will be linked with the installed libpython,
causing it to report an old teeny version in sys.version_info while
staging the install. Then "make package" fails with PLIST mismatches for
{,Pattern}Grammar.*.pickle.

pkgsrc knows which version we're building. Pass that down instead.

For platforms that weren't having this problem, no functional change
intended. For platforms that were, this simply restores "make package",
so no PKGREVISION bump.

Python 3.8.5 final

Security
bpo-41304: Fixes python3x._pth being ignored on Windows, caused by the fix for \ 
bpo-29778 (CVE-2020-15801).

http.client.putrequest(…).

Core and Builtins
bpo-41295: Resolve a regression in CPython 3.8.4 where defining \ 
“__setattr__” in a multi-inheritance setup and calling up the hierarchy \ 
chain could fail if builtins/extension types were involved in the base types.

Library
bpo-41288: Unpickling invalid NEWOBJ_EX opcode with the C implementation raises \ 
now UnpicklingError instead of crashing.
bpo-39017: Avoid infinite loop when reading specially crafted TAR files using \ 
the tarfile module (CVE-2019-20907).

Documentation
bpo-37703: Updated Documentation to comprehensively elaborate on the behaviour \ 
of gather.cancel()

Build
bpo-41302: Enable building Python 3.8 with libmpdec-2.5.0 to ease maintenance \ 
for Linux distributions. Patch by Felix Yan.

macOS
bpo-40741: Update macOS installer to use SQLite 3.32.3.

Python 3.8.4 final

Security
bpo-41162: Audit hooks are now cleared later during finalization to avoid \ 
missing events.
bpo-29778: Ensure python3.dll is loaded from correct locations when Python is \ 
embedded (CVE-2020-15523).

Core and Builtins
bpo-41247: Always cache the running loop holder when running \ 
asyncio.set_running_loop.
bpo-41252: Fix incorrect refcounting in _ssl.c’s _servername_callback().
bpo-41218: Python 3.8.3 had a regression where compiling with \ 
ast.PyCF_ALLOW_TOP_LEVEL_AWAIT would aggressively mark list comprehension with \ 
CO_COROUTINE. Now only list comprehension making use of async/await will tagged \ 
as so.
bpo-41175: Guard against a NULL pointer dereference within bytearrayobject \ 
triggered by the bytearray() + bytearray() operation.
bpo-39960: The “hackcheck” that prevents sneaking around a type’s \ 
__setattr__() by calling the superclass method was rewritten to allow C \ 
implemented heap types.

Library

bpo-41193: The write_history() atexit function of the readline completer now \ 
ignores any OSError to ignore error if the filesystem is read-only, instead of \

Security
bpo-41004: The __hash__() methods of ipaddress.IPv4Interface and \ 
ipaddress.IPv6Interface incorrectly generated constant hash values of 32 and 128 \ 
respectively. This resulted in always causing hash collisions. The fix uses \ 
hash() to generate hash values for the tuple of (address, mask length, network \ 
address).

against header injection attacks.

-c. (discovered via Coverity)
bpo-35975: Stefan Behnel reported that cf_feature_version is used even when \

bpo-40870: Raise ValueError when validating custom AST’s where the constants \ 
True, False and None are used within a ast.Name node.

by TypeError in the in operator and functions contains(), indexOf() and \ 
countOf() of the operator module.

by Jérémy Attali.
bpo-40795: ctypes module: If ctypes fails to convert the result of a callback or \ 
if a ctypes callback function raises an exception, sys.unraisablehook is now \ 
called with an exception set. Previously, the error was logged into stderr by \

incoming connections.
bpo-40055: distutils.tests now saves/restores warnings filters to leave them \
